- Introduction
- ------------
-
- This game was written by myself on a whim, out of total
- boredom. About three days later, this game emerged.
- Currently the game is fairly well debugged, but if any new
- bugs are found, I would appreciate if you tell me. The game
- is a combination of reflexes and mind power, and will hold
- your attention for hours to come.
-
- How to Load
- -----------
-
- After you copy the game to a subdirectory on either a floppy
- or hard drive, type SITRIS to run. The main menu will load
- up.
-
- The Game
- --------
-
- The game of SITris entails various shapes. These shapes fall
- from the top of the screen until they hit something else,
- whether it be another piece or the bottom of the screen. The
- main idea of the game is to maneuver these pieces left and
- right, and position them so that complete rows, or "lines"
- of blocks are created. When a line is fully filled, it is
- removed, and all blocks above it drop down one level. The
- more lines removed with one move, the more points you get.
- If you successfully remove four lines, you achieve
- "HALcyon", and net big points. To aid in the positioning of
- the blocks, the piece may be rotated 90 degrees at a time.
- The game is over when the blocks reach the top of the
- screen.
-
- The Game Screen
- ---------------
-
- When you begin playing the game of SITris by pressing
- <ENTER> at the main menu, the game screen appears. At the
-
-
-
-
-
-
-
-
-
-
- right is a Statistics window telling you how many of each
- individual shapes you've used so far. If so chosen, a window
- on the left will display the next piece that will appear for
- planning its placement. Also on the left are your score,
- lines created, and the level. The level of the game
- increases every time you clear ten lines, and the speed of
- the falling shapes increases with the level. To move the
- piece left and right, the default keys are the left and
- right arrow keys. The down arrow (default) drops the piece
- straight down until it stops - beware, position the piece
- correctly before you drop it, because once it's dropping,
- there is no changing its trajectory. The up arrow (default)
- accelerates the piece downward. And finally, the <ENTER> key
- (default) rotates the piece 90 degrees at a time. These are
- the basic rules of playing SITris.
-
- The Main Menu
- -------------
-
- At the main menu, pressing <ENTER> begins the game. Pressing
- <CTRL-Q> quits and goes back to DOS. Pressing <F1> will show
- you the high score chart. Pressing <F10> will allow you to
- redefine the default keys to your own liking, and once
- redefined, they are saved with the game so that every time
- you load the game in, the new key assignments are loaded as
- well.
-
- You may select various options by using the up and down
- arrow keys to move the pointer, and pressing <SPACE> to
- cycle through the choices for each option.
-
- The first option, Show Next, gives you the option of showing
- the next piece. Turning this option off makes the game
- considerably more challenging.
-
- The second option, SITris Mode, lets you vary the game
- itself. Regular is the standard mode of play, while Small
- shrinks the blocks down to one-fourth the size of Regular.
- Large increases the blocks to four times as large as
- Regular. Wide and Skinny are two modes for those who enjoy
- some variety in their games.
-
- The third option, Starting Level, lets you select the level
- to start the game at. The higher the level, the harder the
- game is - nine is extremely fast.
-
- The fourth option, Starting Height, lets the computer build
- up a tower of blocks as high as you request - 1/3 fills the
- lower one-third of the screen with various blocks, and so
- forth. This lets you practice making lines and lowering the
- entire stack.
-
- The fifth option, Block Set, lets you select which library
- of shapes will be used. Regular is the standard SITris set
-
-
-
-
-
-
-
-
-
-
- of seven shapes, while Extended adds three new shapes the
- the Regular set. Insane! is a completely separate set of
- five entirely new shapes, and All is an amalgamation of
- Regular, Extended, and Insane!
-
- The sixth option, Effects Speed, lets you choose which type
- of special effects you like: the Regular (default) effects
- involve a simple "line removal" effect; the Quick effect is
- a no-frills, quick line removal; the Slow effect is fairly
- interesting, but only if you're in no hurry to play the game
- in a quick fashion.
-
- The last two options, SITris Amoeba and Appearing Blocks
- will be covered below.
-
- Three "comfort keys" are available for use during the game.
- Pressing <CTRL-S> during the game will toggle the sound on
- and off. Pressing <ESC> will quit the game and return you to
- the main menu. And the <PAUSE> key will pause the game; any
- other key will unpause it.
-
- SITris Amoeba
- -------------
-
- The SITris Amoeba is an invisible creature that ravages your
- board. It takes stronghold in a block, slowly disintegrating
- it, and eventually making the block crumble and disappear.
- It can be added to the game to make gameplay more
- challenging. The Amoeba is invisible, but its effects are
- more visible: once it takes hold of a block, you will see
- the block begin to crumble. If not stopped, the block will
- disappear in a few seconds. The only way to kill an amoeba
- is to complete/remove the line that it inhabits.
-
- There are five options under SITris Amoeba:
-
- * Off, which removes the amoeba from gameplay
- * Easy, in which the amoeba randomly affects one block
- during gameplay.
- * Hard, in which the amoeba randomly affects one block, but
- more often than in Easy.
- * Spread, in which the amoeba randomly affects one block,
- then after destroying it, moves on to an adjacent block to
- destroy it, and repeats the process.
- * SprWide is the same as Spread, but the amoeba can move to
- diagonally adjacent blocks as well.
-
- Appearing Blocks
- ----------------
-
- SITris also allows random blocks to appear on the screen.
- These can work either toward or against you. Blocks may help
- in completing lines, but they may also bungle a possible
-
-
-
-
-
-
-
-
-
-
-
- positioning of a block. The options under Appearing Blocks
- are:
-
- * Off: No blocks appear
- * Some: A few blocks appear every once in a while
- * Many: Blocks appear more often than in Some.
-
- What's Next?
- ------------
-
- This is release version 1.0 of SITris. The next version is
- currently in the works, with more streamlined features and
- improved gameplay options.
